GAS HEATER FOR FUR/NACRE., STOVES, 0R APARTMENTS.

Application iled September 13, 1922. Serial No. 537,339.

To all whom t may concern.'

Be it known that l, THEODOR E. KREU'rzER, a citizen of Germany (havingresided in the United States one year last past), and having declared myintention of becoming a citizen thereof, residing in the city and countyof Philadelphia, State of Penns lvania, have invented a new and usefulGyas Heater for Furnaces, Stoves, or Apartments, of which the followingis a specification.

My invention consists of a device embodying a burner adapted to burneffectively commingled inflammable gas and air, the device beingappliable in a furnace, stove or elsewhere, the construction of thedevice being such that the heat is generated in a largel vo u me and ofhigh temperature and adapted to be directed from the furnace, etc., intoan apartment or apartments, the device obviating the use of coal, woodor other fuel, and the expense thereof, while also avoiding the usualattention to a furnace and the-care of its ashes. v

The invention is satisfactorily illustrated in the accompanying drawing,but the irnvportant instrumentalities thereof may be varied, and So itis to be understood that the invention is not limited to the specificdetails shown and described, as long as they are within the spirit orscope of the claims.

Figure 1 represents. a to or plan view partly broken away of a gas urnerembodying my invention.

Figure 2 represents a partial side elevation and a vertical sectionthereof.

Figure 3 represents a side elevation thereof on a reduced scalej showingalso the outlines of a furnace-in which the heater may be placed.

Figure t represents a section of a portion online t-d Figure 2.

Similar numerals of reference indicate corresponding parts in the gures.Referring to the drawings 1 Adesignates the base of the burner, the samebeing a `hollow body ofmetal or other suitable material composed of thebottom plate 2 in the Acentral portion of which is ,theA4` air Hue', 39the. wall of `which forms the er periheral rim 4l which rises from saidplate 2. isi'ng-'from the outer periphery of said plate is the exteriorrim 5,4 said plate 2 and said inner and outer rims t and 5 'thus formingan annulue.

0n plate Gwhich is rested on the rims t and 5 and secured to the bottomplate 2 by 4the bolts or screws 7 which pass through said plates and areprovided with tightening nuts 8.

lin the centre of said plate 6 is the opening 9 which is incommunication with the Hue 3. Connected with the side of the rim 5 isthe top of the .ibase 1 is the covering H the gas supplying pipe 10 inthe length of l .plied with commingled gas and air from the interior ofthe base 1 as is evident.

Above the base is the plate 1 3 of metal or other suitable material andabove the latter is the plate 14 of metal or other suitable marial, saidplates being horizontally arranged separated from. each other and fromsaid base, and are securedn position by the bolts or screws 15 which-pass through ears 16 on the plate 13, ears 17 on the plate 14, and ears18 on the base, and tightened in position by nuts 19 whereby the plates13 and 14C are held elevated firmly above thebase.

ln the plate 13 are the series of vertical perforations or fines 20 andin the plate 1t c are the series of vertical ports, openings or dues 21the parts being staggered in the two plates and! are designed to allowthe products of combustion and air to pass upwardly through the same andtraverse the undersides of said plates respectively in zigzag directionfrom the sets of orts in the plate 13 to the sets of ports in the platelet and thus eectiv'ely heating said plates 1t and 13. f l v 4 lln theouter peripheral wall 5 of the body are the outlet ports 22 which leadfrom. the

interior of the body and allow the commingled gas and air to escapetherefrom at the outer periphery of the body and to be consumed .withthat of the burners 12.

In the inner peripheral wall t of the body are the ports 23 which leadfrom the interior of the body and allow the coled and as to escapetherefrom at the inner perip ery of the body and to be consumed withthat at the burners 12.

'It will be seen that owing to the large voluines of gas andl airsupplied through the burners 12 and by the two courses respectively atthe exterior and centrally of the body due to the ducts 22 and 23 whenthe gas is ignited at the burners, the products of combustion areimpacted against the plates 13 and 1d and passed through theperforations of said plates thus intensifying the heat of the latter andas large volumes of air are furthermore supplied to the burning gas andair the resultant heat is of a large volume and of high temperature andso a rfect combustion is produced, the same ein inodorous in its nature,thus obviating ,in apartments the objectionable smell or odor heretoforecreated in other l gas heated devices of the class.

As the covering plate 6 is a separate mem- `ber from the base it leavesthe latter comparatively cool and so keeps the gas and air pipe 10correspondingly cool. 'll`he perforations in the plates 13 and 1d allowthe products of combustion to pass through them. This assisted byadditional air which also .enters said perforations increases the heatof said combustion thus greatly raising the temperature of said heat asit leaves the device and also consuming the fumes of the combustionwhereby said fumes are destro ed.

'l e air intake 11 consists of a slotted valve plate 2d stationarilyconnected with the gas supply pipe 10 and a slotted valve plate 25rotatively mounted on the neck 26 and placed against the outer side ofsaid plate 2d, so t at. .by rotating said plate 25 the slots of the twoplates may be placed in and out of register so as to adjust the amountof air admitted through the plate 24 and entering the pipe 10, or to cutit od from Athe latter when so required.

The body of the device and its connected appurtenances will be supportedin the furnace, stove, etc., in any suitable manner.

Having thus described my invention what ll claim as new and desire tosecure by lietters Patent, is

1. lin a gas heater, a hollow base coinprising a ottoin plate havingcentrally therein a vertical peripheral rim forming a ilue, and aiiexterior rim and a covering plate resting on said rims and secured tosaid bottom plate, said covering plate havin centrally therein a fluecoincident with said ue of the Fbase and being provided with gas burnergrices, said base havin connected with 1t a g supply pipe, orated pateselevated a ve said cove g late,

lt-like members connected with sai base and rising therefrom andconnected with said elevated plates, and tightenin nuts adaptin saidplates to be supporte sep'- arately roin each other and from said base.

2. lln a gas heater, a hollow base comprising a bottom plate havingcentrally therein', m

'the base and being provided with gas burner orilices, said base havingconnected with it a gas supply pipe, perforated plates elevated abovesaid covering plate, said elevated perforated plates having earsperipherall thereon, bolt-like members in said ears, andy tighteningnuts on said members contiguous to said ears ada ted to connect saidelevated perforated plates with said base and support the formerseparate from each other and from said base.

3. ln a gas heater, a body adapted to receive inainniable gas, the sainebeing of the form of an annulus having outer and inner peripheral walls,a supply member for commingled gas and air connected with said body, agas burner on said body, a plurality of perforated plates sustainedabove said burners, means passed through said plates and through thebase of the body for supporting said plates in spaced relation, said odyhaving therethrou `h an air flue formed by the inner perip eral wall ofsaid body, said wall of said due having therein gas outlet ducts if ingfrom around the upper edge of the body, and the outer peripheral wall ofsaid body having therein gas outlet ducts le il l g from around theupper edge of said body toA said lburner.

4. ln a gas heater, a body adapted to receive inammable gas, the samebeing of the form of an annulus having outer and inner peripheral walls,a gas supply pipe connected with the outer peripheral wall thereof, theinner wall thereof forming through the bodfy an air flue, and 'a closingplate on the top of said body separate therefrom and restin on the topof the inner walls of said y and retained in position on said body, saidplate having therein an air passage which is in communication with saidair flue, a plurality of separated plates above the closing plate, allof said platee havine peripheral ears coincidentall arrang and boltspassed through sai ears and holding au of said plates in speed relation.
